ABSTRACT
Diabetes is a rapidly growing chronic disease that affects more than 220 million people around the world (WHO, factsheet 2011). The serious complications of the disease include lower limb amputations, blindness and cardiovascular disease (WHO, factsheet 2011). Frequent monitoring of blood glucose levels is effective in reducing disease related complications. The current technique for monitoring blood glucose levels involves using the fi nger prick blood glucose test. The limitations of this test are that it is painful and is unable to detect the large fl uctuations in blood glucose levels between sampling time points.
